Moved Gemma4-12B from OpenCode primary model to MCP tool.
This avoids GUI issues and token burn from monitoring.
MCP tool: gemma4
- Calls local llama-server at 127.0.0.1:8081
- Returns reasoning + content
- No API key required
- ~40 tokens/sec generation
Usage: call gemma4 tool with a question, get answer back.
No parent model burns tokens waiting.
